But before you can experience this satisfaction, you need to know how to start your machine. While starting a John Deere D140 might seem like a simple task, there are a few key steps and considerations to ensure a smooth and successful start every time.
This article will walk you through the essential steps for starting your John Deere D140 lawn mower, from preparing the machine and understanding the controls to troubleshooting common starting issues. By the end, you’ll be a pro at firing up your D140 and tackling your lawn care with confidence.
Overview of Starting a John Deere D140 Lawn Mower
Starting a John Deere D140 lawn mower requires a few basic steps:
- Prepare the mower: Ensure the mower is on a level surface, the fuel tank is full, and the blades are disengaged.
- Engage the parking brake: This prevents the mower from rolling while you start it.
- Turn the ignition key to the “On” position: This powers the electrical system.
- Press the choke lever (if necessary): This enriches the fuel mixture for easier starting in cold conditions.
- Turn the ignition key to the “Start” position: This engages the starter motor, which turns the engine over.
- Release the choke lever (once the engine starts): This allows the engine to run smoothly.
Important Note: The specific steps and controls may vary slightly depending on the model year and features of your D140. Always refer to your owner’s manual for the most accurate information.
Preparing Your John Deere D140 for Starting
Before you attempt to start your John Deere D140, you need to prepare the machine to ensure it’s ready to go. This involves checking a few key components and making sure they’re in good condition.
1. Checking the Fuel Level
H3. Ensure a Full Tank for Smooth Operation:
The first step in preparing your D140 is to make sure you have enough fuel. A full tank will provide ample power and prevent the engine from stalling mid-mow.
H4. Recommended Fuel Type:
John Deere D140 mowers typically recommend using unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol-blended gasoline as it can cause problems with the fuel system.
2. Inspecting the Blades
H3. Sharp Blades for a Clean Cut:
Dull blades not only result in uneven cuts, but they also put extra stress on the engine and can damage your lawn.
H4. Sharpening or Replacing Blades:
If your blades are dull, you can sharpen them yourself with a file or take them to a professional for sharpening. If the blades are severely damaged, they should be replaced.
3. Ensuring a Level Surface
H3. Stability for Easy Starting:
The D140 needs a stable platform to start properly. Make sure the mower is parked on a level surface to prevent it from rolling while you’re starting it.
H4. Adjusting the Deck:
If the mower is parked on uneven terrain, you can adjust the deck to level it out. This will ensure that the blades are cutting at the correct height.
Starting Your John Deere D140 Lawn Mower
Now that your D140 is prepped and ready, you can begin the starting process.
1. Engage the Parking Brake
H3. Preventing Roll-Away:
The parking brake is a safety feature that prevents the mower from moving while you’re starting it. Ensure the brake is engaged by pulling the lever up and securing it in place.
2. Turning the Ignition Key
H3. Powering Up the Electrical System:
Locate the ignition key on the dashboard, typically near the steering wheel. Insert the key and turn it to the “On” position. This will power up the electrical system, including the lights and gauges.
3. Choking the Engine (If Necessary)
H3. Enriching the Fuel Mixture:
The choke lever is a small lever located on the dashboard, typically near the steering wheel. This lever controls the amount of air entering the engine, which helps it start more easily in cold conditions.
H4. When to Use the Choke:
If your engine is cold, you’ll need to engage the choke lever before starting it. This will enrich the fuel mixture, making it easier to ignite. Once the engine starts, release the choke lever to allow the engine to run smoothly.
4. Turning the Ignition Key to “Start”
H3. Engaging the Starter Motor:
With the ignition key in the “On” position, turn it to the “Start” position. This will engage the starter motor, which turns the engine over.
H4. Holding the Key in “Start” Position:
Keep the key in the “Start” position until the engine starts. If the engine doesn’t start after a few seconds, release the key and try again.
5. Releasing the Choke Lever
H3. Adjusting the Fuel Mixture for Smooth Operation:
Once the engine starts, release the choke lever gradually. This will allow the engine to run smoothly and adjust to normal operating conditions.
Troubleshooting Starting Issues
While starting your John Deere D140 should be a straightforward process, there are some common issues that can arise.
1. The Engine Won’t Start
H3. Checking for Common Issues:
If your engine won’t start, there are a few things you can check:
- Fuel: Ensure the fuel tank is full and there’s no blockage in the fuel lines.
- Battery: Make sure the battery is charged and has good connections.
- Spark Plugs: Check the spark plugs for wear and tear, and replace them if necessary.
- Starter Motor: Ensure the starter motor is functioning properly.
2. The Engine Starts But Immediately Dies
H3. Addressing Potential Problems:
If the engine starts but dies immediately, check the following:
- Choke: Make sure the choke lever is released once the engine starts.
- Fuel: The fuel system may have a blockage or the fuel filter may be dirty.
- Air Intake: The air filter may be clogged, restricting airflow to the engine.
3. The Engine Runs Rough
H3. Diagnosing the Issue:
If the engine runs rough, it could be due to:
- Spark Plugs: Worn or faulty spark plugs can cause rough running.
- Fuel System: A clogged fuel filter or dirty carburetor can also contribute to rough running.
- Air Filter: A clogged air filter can restrict airflow and cause the engine to run poorly.

Frequently Asked Questions
Here are some frequently asked questions about starting a John Deere D140 lawn mower:
1. What are the basic steps to starting a John Deere D140?
The John Deere D140, like most lawn mowers, requires a few basic steps to start. First, ensure the fuel tank has sufficient gasoline and that the choke is engaged. Then, turn the key to the “on” position and prime the engine by pressing the fuel primer bulb several times. Once primed, pull the starter rope slowly until you feel resistance, then pull it quickly and firmly. If the engine doesn’t start, repeat these steps, making sure to adjust the choke position as needed.
2. How do I check the oil level?
Checking the oil level on your John Deere D140 is essential for its proper function. Locate the dipstick near the engine and pull it out, wiping it clean with a cloth. Reinsert the dipstick fully and pull it out again to check the oil level. The oil should be within the “Full” and “Add” markings. If it’s below the “Add” mark, add oil until it reaches the “Full” mark. Ensure you use the correct type of oil recommended in your owner’s manual.
3. Why won’t my D140 start?
Several reasons could prevent your John Deere D140 from starting. A common issue is an empty fuel tank. Ensure you have enough gasoline and that the fuel line is unobstructed.
